Definitions

  • the invention relates to a method for producing a vacuum panel, as well as a Such vacuum panel, especially for thermal insulation purposes.
  • such a vacuum panel consists of a single or multi-walled gastight envelope and a filling of granular or powder degassed Support elements, wherein the interior of the shell is evacuated, wherein the support elements are close together and are tightly surrounded by the shell.
  • Such vacuum panels are known in many forms, for example EP 0 106 103 A1, US Pat. No. 4,668,551, WO 00/71849 A1.
  • Such vacuum panels are used for thermal insulation between each other heat-insulating surfaces brought to the plant.
  • they will placed between two shells of a multi-walled brick or in one Component introduced, one part of which is outboard and the other part is internal, these two parts are preferably thermally separated, such as in window frame assemblies and the like, such as for example, not exhaustively listed in the aforementioned WO 00/71849 A1 are.
  • the single-layer or multi-layered shell is not sufficiently gastight, so that the ingress of gas from the environment Vacuum within the envelope is impaired, even when installed, so that the thermal insulation decreases.
  • the shell is especially at Shoring, that is the attachment between heat-insulating against each other Surfaces prone to injury, especially in the contact area to these surfaces.
  • a vacuum panel be improved so that the functionality, in particular the Thermal insulation achieved with higher security, or a longer period of time can be.
  • this object is achieved by a method for producing a vacuum panel with the features of Claim 1, as well as by a corresponding vacuum panel according to the Features of claim 19.
  • Essential for this aspect of the present invention is that through the surface-side glass forming a vacuum panel is created that does not have seams has and has a fairly durable surface.
  • the object is achieved according to a second aspect of the invention by a method with the features of claim 5 and a vacuum panel with the features of claim 23 solved.
  • This aspect of the present invention is achieved by the corresponding dependent claims.
  • This aspect of the invention is based on the knowledge that with a partial coating, occupancy or planking the surface of a vacuum panel with sheath security against Reduction of the vacuum by "outgassing" on the one hand and the protection against On the other hand, injury during shoring is greatly increased, but no thermal bridge between mutually heat-insulating surfaces is created.
  • An amount of starting material 1, for example a powdery or granular Material is first pressed in a first step S1 into a mold, For example, a plate or cuboid shape, as in later Use cases is to use.

  • this glass layer is solidified by cooling in accordance with step S5, then the Glass layer and thus provides a closure for that within the glass layer, that is, inside the plate, between the unmelted ones arranged there Particles of the starting material reached vacuum.
  • melts typically attempt to contain them inside Gas residues and / or residual liquid to escape and lead to unwanted Openings. It is therefore expedient, after melting in accordance with step S2 to selectively provide openings 3 (FIG. 2) in the glassy surface such that evaporating moisture and gases can escape easily, like that through the Steps S3 and S4 is shown.
  • step S5 After cooling according to step S5, it is only necessary the openings. 3 to close, which is shown in Figure 2 by closure elements 4.
  • This Closing has, as shown by step S6, after an evacuation, if necessary, to be evacuated again.
  • a vacuum panel 2 inside by the particles formed the starting material 1, closely abutting supporting elements 12th contains, between which there is a vacuum, wherein the arrangement of the support elements. 2 is completed gas-tight to the outside through a glass layer 5 and possibly provided openings 3 are closed by closure elements 4. That way formed vacuum panel 2 is therefore characterized by a glass skin and has no seams on. This glass skin forms a very hard-wearing layer 5. Such formed vacuum panels 2 can therefore be further processed in a simple manner become.
  • Particularly suitable as support elements 12 are silica particles.

Of the Interior of the shell 11 is evacuated, whereby the support members 12 close together approach and are surrounded by the shell 11 tight fitting.
  • the material of Supporting elements 12 is of course made of a heat-insulating material, as well as the shell 11.

  • this additional layer 14 is essential that it the gas tightness of the shell 11 to the relevant sections substantially increased while contributing to Heat insulation itself does not have to be done. It can therefore be compact Materials such as metal foils or metal layers, such as a Aluminum foil. Such a material is relatively unreliable in terms of Injuries in the shoring, that is, in terms of the risk, during installation such to be damaged, that the tightness of the shell 11 is impaired.
  • the above-mentioned adhesive bond may be a ceremoniverklebung exclusively used for assembly purposes, if the heat-insulating surfaces against each other having components not shown in any other way with each other are connected, appropriately thermally decoupled connected to each other.
  • the seam 13 is vulnerable to damage in a special way, at least during installation. It is therefore expedient, as shown, also the interface, which is formed by two interconnected tabs 15 and 16, also additionally provided with an additional layer 17 or 18, where appropriate the arrangement is such that the coated tabs 15, 16 on the additional Layer 14 are foldable. Appropriately, in the associated the against each other heat-insulating surfaces a corresponding recess be provided.

  • Fig. 5 shows in perspective an arrangement in which the through the vacuum panel 10th formed thermal insulation is essentially cuboid, so a clear Thickness dimension has.
  • a comparatively elastic shell instead of a comparatively rigid box or box-like sheath arrangement be selected which is evacuated via a nozzle or the like (not shown).
